Lecture given by Dr Saithna, Orthopedic Surgeon, Overland Park, Kansas on his latest research related to knee and shoulder injuries, including: Anterior cruciate ligament (ACL), ACL repair, ACL reconstruction, ACL rehabilitation, Rotator cuff and Long head of biceps injuries
Background: Distal femur fractures make up 6 to 7% of all femur fractures. Various plating options for distal femur fracture are conventional buttress plates, fixed-angle devices, and locking plates. This study was planned to evaluate and explore locking compression plate fixation in distal end femur fractures which is expected to provide a stable fixation with minimum exposure, early mobilization, less complications and a better quality of life.
Methods: The study was conducted as prospective clinical study in 20 skeletally mature patients with x-ray evidence of distal femur fracture fulfilling inclusion and exclusion criteria, operated with distal femur LCP plating. Patients were assessed radiologically and classified according to distal femur fracture classification and outcome graded as excellent, good, fair and poor based on Lysholm Knee Score.
Results: Out of 15 excellent outcome cases, 3 cases were type A1 fracture, 1 case had type A3, 2 cases had type B1 and B2 each, 5 cases had type C2 and 2 cases had type C3 fracture. 1 case with good outcome was type C3. 1 case with fair outcome was type B2. While 3 cases with poor outcome were type A1, A2 and C3.
Conclusions: The DF-LCP is an ideal implant to use for fractures of the distal femur. However, accurate positioning and fixation are required to produce satisfactory results. We recommend use of this implant in Type A and C, osteoporotic and periprosthetic fractures.

Cautious optimism following SCR may be offered to this challenging subset of patients with symptomatic irreparable rotator cuff tears. It is likely that the relatively low re-operation rates can be further improved by considering the negative prognostic factors in defining indications for surgery. Further studies with longer term followup are recommended.

Introduction: : Hand Tendon injuries are not uncommon. Achieving a satisfactory range of motion and preventing tendon rupture after repair of flexor tendon injuries remains a challenge to hand surgeons..Objectives: To compare functional outcome of tendon repair with Modified Kessler and four strand cruciate techniques.Material and Methods: Randomized control trial was conducted from July 2013 to June 2015. Both male and female patients of age 18 to 60 years who had clean lacerated injury proximal to wrist crease (Zone V) were eligible for inclusion in the study. Patients with dirty or infected wounds, or those having multiple injuries other than tendons, having injury to extensor tendons were excluded from the study. Arm A comprised of patients who underwent modified Kessler repair and Arm B included patients whose repair was done via four strand cruciate repair technique. The final outcome at 8 weeks was compared by using Strickland’s evaluation system. Results: A total of 140 fingers of 44 patients with sharp wrist laceration injury of long flexor tendons of fingers were included in this study. The average age of patients was 28.05 ± 10.42 years. Out of 44 patients, 28 (63.64%) were males and 16 (36.36%) females. At 8th week, satisfactory functional outcome (excellent group according to Strickland evaluation) was observed in 65.7% (46/70) fingers in four strand cruciate repair technique and in 28.6% (20/70) fingers in standard modified Kessler repair technique and the difference was statistically significant (P<0.001). Conclusion: Four strand cruciate repair technique is better than standard modified Kessler method for repair of long flexor tendons of fingers.

Healing rates of the posterior horn of the lateral meniscus appear to be less favourable than other locations. In part this is due to the loose capsular attachment in this region reducing the success of deployment of anchors on the capsule. Using popliteus as an anchor point is safe and results in a very low rate of re-operation for failure of repair

ACL repair offer several potential advantages over ACL reconstruction (including quicker rehabilitation, less invasive surgery, reduced operative time, avoidance of donor site morbidity, better proprioception, better forgotten joint scores and the simplicity of revision to ACL reconstruction if the repair fails). This study compares the clinical outcomes of ACL Repair vs Reconstruction. It demonstrates several advantages of ACL repair including superior muscle strength at 6 months, and significantly better forgotten joint scores (FJS-12 scores) as well as non-inferiority with respect to knee laxity parameters and the IKDC score.

NJR data reports that the majority of surgeons use a cemented stem for hemiarthroplasty in fractured neck of femur patients. For those that use an uncemented implant this simple tool can help predict those patients in whom the risk of fracture is high and where a cemented implant should be further considered.
Introduction: The radiological work-up of patients with patellofemoral disorders continues to be debated. The interchangeability of the tibial tubercle-trochlear groove (TT-TG) distance between computed tomography (CT) and magnetic resonance imaging (MRI) has recently been questioned. In addition, a new measurement-the tibial tubercle-posterior cruciate ligament (TT-PCL) distance-has shown that not all patients with a pathological TT-TG distance (>20 mm) have lateralization of the tibial tubercle. Another factor to consider when looking at the position of the tibial tubercle is the knee joint rotation, defined as the angle between the femoral dorsal condylar line and the tibial dorsal condylar line.
Aim: To determine, with a larger population, if the TT-TG measurements can be used interchangeably between CT and MRI and to confirm the correlation between the TT-PCL and TT-TG distances in determining tibial tubercle lateralization.
Study Design: Cohort study (diagnosis); Level of evidence, 2.
Patients with patellofemoral disorders and MRI and CT scans of the same knee (n = 141) were identified. The TT-PCL, the knee joint rotation, and TT-TG were measured independently by 2 fellowship-trained orthopaedic surgeons. Thirty measurements were repeated on a separate occasion to allow for an assessment of the intrarater reliability. The intraclass correlation coefficient (ICC) was used to assess reliability of the measurements.
Results: The mean TT-TG was 4.16 mm less on MRI (P < .05), with the mean TT-TG ± SD being 17.72 ± 5.15 mm on CT (range, 6.97-31.33 mm) and 13.56 ± 6.07 mm on MRI (range, 2-30.04 mm). The ICC for each rater comparing the 2 imaging modalities was only fair (0.54 and 0.48). The mean TT-PCL measurement was 20.32 ± 3.45 mm (range, 10.11-32.01 mm) with excellent interobserver and intraobserver reliability (>0.75). Based on the TT-TG and TT-PCL measurements, 4 groups of patients can be established. When knee joint rotation is compared among groups, an increased TT-TG may result from true lateralization of the tibial tubercle, an increased knee joint rotation, or both.
Conclusions: Based on a statistically significant mean difference (4.11 mm) and only a fair ICC (0.54 and 0.48) for raters comparing the 2 modalities, the measurements for the TT-TG cannot be used interchangeably between CT and MRI. Therefore, currently accepted values for TT-TG based on CT scans should not be applied to an MRI scan. The TT-PCL measurement is a measure of true lateralization of the tibial tubercle, while the TT-TG is an amalgamated measure of true lateralization and knee joint rotation.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

1. Lack of significant proven clinical benefit
2. Concerns regarding poor outcomes and high complication rates
– donor site morbidity
– overconstraint
– cosmetic problems
– stiffness
– increased risk of septic arthritis
– long-term chronic pain and swelling
– poor long-term functional outcomes with lower subjective and objective results

6. Rehabilitation
Same protocol for all 3 graft types:
• brace-free, immediate full weight bearing
• early rehabilitation focused on obtaining full extension
and quadriceps activation
• Gradual return to sport activities allowed
– non-pivoting sports – 4 months
– pivoting non-contact – 6 months
– pivoting contact sports – 8-9 months
7. Results (n=502)
Mean age 22.4 +/-4.0 years (range 16-30 years), 72.5% male (n=364)
Mean follow up 38.4 +/- 8.5 months (range 24-54 months)
No significant differences between each of the groups with respect to:
• mean time between injury and surgery (P = .73)
• preoperative side-to-side laxity (P = .73)
• rate and type/location of meniscal tears (P = .32) (25.4% of the patients had a
medial meniscal tear, 15.4% had a lateral meniscal tear, and 12.8% had tears of
both menisci)
• surgical treatment for meniscal tears (2.8% medial meniscectomy, 35.4% medial
meniscal repair, 4.3% lateral meniscectomy and 23.9% lateral meniscal repair).
11. Conclusion 1:
Combined ACL + ALLR is associated with a 2.5 to 3
fold reduction in ACL graft rupture rates when
compared to isolated 4HT or BTB ACLR

14. Conclusion 2:
ALLR protects repaired medial meniscus: Two fold reduction
in re-operation for MM repair failure in patients with
ACLR+ALLR compared to patients with isolated ACLR (hazard
ratio, 0.443; 95% CI, 0.218-0.866).
16. Rationale for improved results compared to historically poor
outcomes:
Less Invasive & More Anatomic
17.
18. • 3/548 (0.5%) of patients had a complication specific to ACL+ALLR
and all involved femoral hardware
- Patient 1: femoral screw too long
- Patient 2: persistent pain
- Patient 3: posterior wall blow-out
- All patients made a full recovery after screw removal
- No re-operations to cut a tight graft
Specific Complications
19. Comparison to studies reporting re-
operation after isolated ACLR
• Kartus et al, (n=604)
• follow up ranging from 2-5 years
• re-operation rate 26.7%
• Hettrich et al, MOON study group
(n=980)
• follow up 6 years
• re-operation rate 18.9%
21. Conclusions
1. Combined ACL + ALLR is associated with a 2.5 to 3 fold
reduction in ACL graft rupture rates when compared to
isolated ACLR
2. ALLR protects repaired medial meniscus: Two fold reduction
in re-operation for MM repair failure
3. ACL+ALLR has a very low rate of specific complications
4. Re-operation rates after ACL+ALLR are broadly comparable
to published rates after isolated ACLR
5. High rates of stiffness and re-operation noted historically
were not observed in this series
